Palladium-catalyzed carbonylative annulation reaction of 2-(1-alkynyl)benzenamines: selective synthesis of 3-(halomethylene)indolin-2-ones.


A novel and selective palladium-catalyzed carbonylative annulation process for the synthesis of 3-(halomethylene)indolin-2-ones was demonstrated. In the presence of PdX2 and CuX2, 3-(halomethylene)indolin-2-ones were selectively obtained from the carbonylative annulations of 2-(1-alkynyl)benzenamines with CO in moderate to good yields.
